Researchers say the ancient breakup of tectonic plates creates churning waves in Earth’s mantle that tumble in slow motion under the continents for tens of millions of years, sculpting topography deep within continental interiors.

For #DNADay: Welcome to the nanosize railway. Much as a train switchyard can steer rail cars to different locations, researchers have engineered protein motors to carry tiny bits of cargo to different locations. In the body, protein motors ferry nutrients and other materials along tiny tube-shaped rails that crisscross cells. Nanotechnologists have made their own versions for years using tube-shaped rails made from DNA. Last year, researchers took that approach one step further, creating DNA nan

In a lab in central Pennsylvania, a fly is suspended in a magnetic field inside a dome lined with rotating LED bulbs. The insect flaps its wings and spins, believing it’s actually buzzing through this virtual reality environment—one that can even distort what the fly sees. Though unusual, this tiny virtual reality flight simulator has a deeper purpose. Here, researchers are probing the inner workings of the insect brain. The study, published last month in Current Biology, reopens a “long-standin

Rattlesnakes in arid landscapes often coil their bodies when it rains to gather and sip drops from their sticky scales. But they can also nab water from the skin of nearby snakes, according to a new study reported in Current Zoology. To make the find, biologists studied 100 prairie rattlesnakes (Crotalus viridis) on a high-elevation ranch northwest of Steamboat Springs, Colorado. The team mimicked the area’s sporadic showers by spritzing the snakes with a garden sprayer, then recorded their reac

Elephants love showering to cool off, and most do so by sucking water into their trunks and spitting it over their bodies. But an elderly pachyderm named Mary has perfected the technique by using a hose as a showerhead, much in the way humans do. The behavior is a remarkable example of sophisticated tool use in the animal kingdom. But the story doesn’t end there. Mary’s long, luxurious baths have drawn so much attention that an envious elephant at the Berlin Zoo has figured out how to shut the w

In 1986, scientists discovered odd structures in cells they dubbed vaults. They’re found by the thousands in many cells in a diversity of species. Decades later, the function of vaults remains mysterious, but synthetic versions could act as delivery vehicles for cancer drugs and gene therapy. To learn more, click the link in our bio.
